Lanbo Normal Refrigerant Flow Noise or Possible Low Charge

Unit runs but makes a gurgling or hissing sound inside the cabinet.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Normal expansion of refrigerant in evaporator, Slightly low refrigerant charge, Air in sealed system

Some gurgling or hissing is normal in refrigeration systems, especially during start and stop.

1. Observe performance:
- If the cooler maintains proper temperature, the noise is likely normal.
2. Check for cooling issues:
- If cooling is poor and noise is excessive, there may be a sealed-system issue.
3. Do not attempt sealed-system repairs yourself:
- Contact a licensed refrigeration technician to check refrigerant charge and system integrity.
